7/17:Tigers closer Justin Wilson is one of the trade deadline's most enticing pieces. He's being given a serious look by both the Nationals and Rays. The lefty was promoted to closer when the bottom fell out on Francisco Rodriguez earlier in the year and Wilson has struck out 50 batters over 35 innings. Despite the pickups of both Sean Doolittle and Ryan Madson this weekend, the Nats are still hunting for a legitimate top-shelf closer. They didn't give up any of their top five prospects over the weekend, so this is worth keeping an eye on.--Mario Hernandez - RotoBallerSource: Twitter
